8 / 33 page Pin description STLED316S 8/33 2 Pin description Figure 3. STLED316S pin connection Table 2. Pin description Pin number Symbol Type Name and function 1 DIN/DOUT IN/OUT Output serial data at falling edge of the shift clock, starting from lower bit. Input serial data is clocked in at rising edge of the shift clock, starting from lower bit. 2CLK IN Reads serial data at rising edge, and outputs data at falling edge. 3STB IN Initializes serial interface at rising or falling edge to make STLED316S wait for reception of command. Data input after the falling edge of STB are processed as a command. While command data are processed, current processing is stopped, and the serial interface is initialized. While STB is high, instructions are ignored. 4IRQ_N OUT Interrupt output (active low) to interrupt the MCU when there is a key press 5 DIG1_LED OUT Single output LED used together with the 8 segments to drive up to 8 discrete LEDs 6,7,8 DIG2, DIG3, DIG4 OUT Digit output pins. 9VCC PWR 5.0 V ± 10% Core main supply voltage. Bypass to GND through a 0.1 µF capacitor as close to the pin as possible. 10,11,12 DIG5, DIG6, DIG7 OUT Digit output pins. |
